Blender to Unity, Animations are exporting 2x
Okay so the only way I know of doing this is putting al of your animations in the NLA window. Like so.



After that you can export the Armature + Model.

Deselect - All actions

Select - NLA Strips ( in which you put the animations )



That way, when you import it into unity you will only get the animations that were pushed down on the NLA strip.
